A sample of BCC metal is placed in a X-ray diffractometer using radiation with wavelength of 1.541 A. For a diffraction angle 2θ = 101.502º, a diffraction is obtained from the planes [310]. Calculate the value of the network constant a and say which of metals in the table is the one studied, n = 1.
\begin{tabular}{lc} \hline Metal & Constante de red a( nm) \\ \hline Cromo & 0.289 \\ Hierro & 0.287 \\ Molibdeno & 0.315 \\ Potasio & 0.533 \\ Sodio & 0.429 \\ Tántalo & 0.330 \\ Volframio & 0.316 \\ Vanadio & 0.304 \\ \hline \end{tabular}
